To all whom it may concern:

Be it known that I, O'r'ro BECKER, a citizen of the United States, residing at New York, in the county of New York and State of New York., have invented new a'nd useful Improvements in Bottle or Jar Closures, of which the following isa specification.

This invention relates to improvements in bottle or jar closures of that type in which the bottle or liar is formed with two or more spaced shoulders having inclined lower edges for use in connection withv a closurecap rovidedI with. a corresponding number of' ugs or projections adapted to bind against the inc .ined edges of the shoulders to secure the ca in position.

he primary object of the present invention is to provide a novel construction of cap in which the locking members thereon are formed byvprimary integral extensions from the flan e of the cap, which are rolled in the form off beads to engage the inclined edges of the shoulders, thus providing loclting members which may be conveniently formed and which are of maximum strengt to withstandthe strain imposedY thereon when the cap is turned tightly into wedging engagement with the inclined surfaces of the shoulders. V

The invention consists of the features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accom panying drawing, in whic 1- Figure 1 is a side elevation of the upper portion of a bottle or jar with the cap aplied thereto, the cap appearing in section. ig. 2 is a similar view at right an les to that shown in Fig. 1. Fig. 3 is a to p an view of the neck of the bottle or jar. ig. 4 is a bottom plan view of the ca Fig. 5 is a fragmentary section throng the cap showing one of the lips or extensions rior to its formation into the locking bea Fig, is` a section through the cap on an enlarged scale, showing in detail the form of the bead.

Referrin indicates t e upper portion of a bottle, jar, or other suitab e receptacle, which may be of any desired form. The neck or `extreme upper end of said recepltacle is formed'with two or more external s oulders 2, se arated by intervening spaces 3, each of sai shoulders having an lnclined lower edge 4, such edges inclining inwardly and downwardly -in to the drawing, the numeral 1` the same general direction around the neck of the bottle.

The cap 5 is formed of sheet metal and is generally of the ordinary shape, having a crown portion 6 and a depending flange 7, which latter may be formed around its. circumference with a series of integral projections 8 to provide a milled or serrated gri ping surface to enable it to be secure y grasped and readily turned in opposite directions for application and removal.

The {iange 7 of the cap is provided at its lower edge with inwardly extending locking projections 9 equal in number to the shoul ders 2 andv adapted to engage the inclined surfaces 4 thereof. The said locking pro- 'eetions are so relatively arranged asto be rought into alinementl with the recesses 3 betweenA the ends of the shoulders, so es to allow the cap to be slipped down upon the neck with. its flange surrounding the same `and inclosing the shoulders, whereby upon rotating the cap to the right the locking projections will ride upon and.r bind or wedge against the inclined surfaces of the shoulders, thereby drawing the usual sealing disk 10 closely down against the upper end of the neck and locking the cap securely in applied position. Upon turning the capto the left to bring the projections 9 into alinement with the recesses, the cap may be removed in the usual manner.

In accordance with my invention the lockin projections 9 are formed integral with t e flange of the cap by initiallyproviding said flan e `with dependino li s or extensions, as shown in Fig. 5, wlliic i liis or extensions are turned or rolled inward y or upwardly'into the form of a bead, .as shown in Fig. 6, within which is inclosed a circular reinforcing wire 9 to render the bead nonresilient and provide a bead ofV maximum` strength. As shown, the beads thus provided u on the flange of the cap lie upon the inner sigo of the flange with their lower surfaces substantially flush with the lower edge thereof and their upper surfaces formed to squarely engage the inclined edges 4 of the shoulders.

In order to tightly seal bottles and jars of certain kinds, 1t is necessary to have the beads or locking pro'ections bind with reat force against the inclined lower edges o the shoulders 2, in order to draw the top of the cap and the sealing disk down close upon the mouth o f the bottle or jar. Whenatight binding action of this character is set up, the pressure upon the beads tends to cause the eads to be forced open Aor the top of the cap to buckle through the transmitted strain from the flange. This objectionable tendency of the beads to be forced o en or to yield undul and prevent 'the desu-cd tight closure of t e cap is liable to occur on account of the thinness of the metal necessarily em loyed, and, of course, such tendency would be increased were the beads loosel rolled or unreinforced, or rolled so that thelr free edges would simply contact with the bod of the flange or lip so that said free edge wou d be subject to unrestricted depression under the pressure of its wedging en agement with the inclined surface of the s oulder on the neck. A portion of this objection is avoided in the present structure by render ing each bead non-resilient by arranging the stifening wire therein, so as to material y restrict or prevent depression of the bead as a whole, as well as the free edge thereof, and this wire also stiens the adjacent portion of the flange of thel cap to assistit in withstanding the compressing strain. This action is further promoted by turning the free edge of the bead downward into the V-shaped space or crevice between the outer vertical body portion of the lip and the upper outer surface of the stiening wire, as clearly shown in Fig. 6, so that t e binding pressure falling on said free ed ge of the bead will force the same more firmly mtovsaid sp ace and contract the bead so that it will more firmly embrace the wire and thus be prevented from ringing or yielding under such pressure.

he integral projectlons 8 are also made of some materia length, so that they will rein.- force the flan e between the beads and crown of the cap thus prevent any tendency of the crown to buckle or the flange toextend and permit the beads to unfold under severe pressure. I am aware that it has heretofore been proposed to employ rolled locking beads and to vertically corru ate the llange of the cap, but I believe that am the first to construct and reinforce the beads in the manner described and to employ vertical projections or corrugations on the flange above the beads to coact with the latter in the manner set forth.

It will be seen from the foregoing description that a ca of simple construction is provided in whic the locking projections are of reater length than ordinary to increase the rictional engagement between the cap and shoulders, and that by formin such proection in the manner described t ey are e ectually adapted to withstand the strain fallin thereon from their wedging engagementwit l the shoulders. It will be obvious that the caps with the straight lips thereon may be readily struck up through the action of a die, and the beads then formed by ceiling the lips in any convenient manner.

Havin thus fully described the invention, what is c aimed as new is A bottle having external shoulders spaced apart a like distance and oppositely inclined at their lower edges, in combination with a sheet metal closure therefor having allange to encircle the shouldered portion of the bottle, and having lips pendent from said flan e, and inwardly rolled and circumferentially curved to form locking proections to en age the inclined edges of sald s oulders, and ongitudinally curved reinforcements filling the` rolled. lips to render them ri 'd and to c amp the edge portions of the lips etween said reinforcements and the inc ined edges of said shoulders.

In testimon whereof I ax my signature in presence o two witnesses.

OTTO BECHER.
